Preservative Treated Plywood

Certain construction environments demand more than standard materials can offer. When wood is exposed to moisture, soil contact, insects, marine environments, or extreme decay conditions, preservative-treated plywood becomes essential. Selecting the right treatment type, retention level, and use category can make the difference between a structure that lasts and one that fails prematurely.
